In this episode, Steve and Bill discuss the role of the Holy Spirit in bringing salvation to the human race through the person of Mary on whom the Holy Spirit descends to incarnate the second person of the Godhead, Jesus Christ. This is understood as the "economy" or the role of the Spirit as the one who does not manifest Himself, but reveals Christ. But then something happens during the second break and... well, don't reveal the suprise ending of this program to anyone.
